Tasmota Rule Examples

Below are some rules for Tasmota that I’ve used over the years, including doing basic standalone automations (no Home Assistant, no Node Red, or other additional tools). Standalone automation can be handy, and in simple cases you don’t need any working wireless for basic functions. If you install smart devices, you can safely disconnect your networking (eg if you sell your house) and still have some basic smart functions.

Oven Reminders with Node Red & ESPHome

Use of Node Red and Javascript to monitor power to my oven and give regular announcements that is is still running. It also can log to a csv file and do calculations based on total power used and the cost of that power, with peak/offpeak rates taken into account.

WB3S replacement for Home Automation devices

More and more home automation devices from China are coming with no ESP8266 module, especially the TUYA based ones. Some are coming with a WB3S (which is different to the TYWB3S), but this can easily be removed and replaced with a cheap ESP12F (or similar) module.

Kogan Smart Plug: No Esp8266? (Tuya WB2S)

It is getting more and more common to get smart devices that have chips other than ESP8266 in them, and these chips are usually not flashable with the likes of Tasmota, espHome etc. This Kogan power monitor had an Tuya WB3S

Smartphone screen protector UV cured

I have had various phone screen protectors over the years, floppy and solid and preferred the solid glass cover I had on on my Note 8 for over a year I paid NZ$30+ for the last one including install by someone at a ‘phone shop’ but really it wasn’t a nice install, and I re-seated it not long to try…

Whole House 3 Phase Power with PZEM-004T

A robust, accurate, low cost and safe whole house electricity monitoring setup, using PZEM-004T modules. These use current transformers (CTs), and send data as TTL Modbus-RTU. Recently Tasmota has added support for up to 3 of these directly (on the same data channel) so there are fewer hoops to jump though to get them working (previously my testing involved sending serial commands)

Over Stair TV Cabinet + Hall Storage

Because I hate unused space… I decided to plan a storage unit for above where our stairs go from our lounge to the lower level. There is decent ceiling height here, and the back of the area is accessible from the hallway. We thought of the concept when we were renovating the hall about 12 months previous, and so cut…

How to Stop Your Caravan From Disappearing

Caravan thefts in New Zealand have become a lot more common in the past few years, and every day or so you hear about another one going missing. Caravans are pretty easy to steal by themselves, as they are light weight, usually easily accessible on a driveway… and they sit home alone when people go to work. An often touted…

1965 Zephyr Deluxe Caravan Restoration

These are the before and after photos of our 1965 15″ Zephyr Deluxe Caravan. It was apparently stored in a shed for 20 years so apart from some general decay, some borer and a bunch of broken and missing stuff, the layout and fittings were mostly original. We had it mostly as we got it for a couple of years…

Upgrading a 5 Year Old Samsung Galaxy S2 to Android M

I needed a phone for my son as he had been given an older ZTE V795 phone running Android Gingerbread. The ridiculous thing about this is that besides the fact there is really no way to easily upgrade or change out the ROM on this phone… you can’t even update the current setup as any ‘play store’ updates fail even…

Dashcams… and the $80 Mobius

The proliferation of small sports cameras, ‘dash’ cams and security cameras has meant that Youtube abounds with footage of incidents, near misses, ‘oh %$#@’ moments, and just generally people and drivers doing stupid things.

iPad and iPhone tips

Just a repost from a technology site.  I guess if you have an iPad these are useful things to know.  I think they have hyped it up a bit… they aren’t exactly ‘mind-blowing’!  Interesting and mostly helpful all the same.

Bitcoin…. it’s not magic

Bitcoin has been mentioned in the mainstream media recently as a ‘new form of electronic money’.  It sounds impressive, but the way it works as a system of ‘money’ is actually not that impressive and easy to explain if you take the ‘tech’ side away.
